  • Why is nesting or piggybacking errors within errors bad in general?

    - by dietbuddha
    Why is nesting or piggybacking errors within errors bad in general? To me it seems bad intuitively, but I'm suspicious in that I cannot adequately articulate why it is bad. This may be because it is not in general bad and that it is only bad in specific instances. Why is it detrimental to design error/exception handling in such a way. The specific instance is that of a REST service. There is a desire by some to use http errors (specifically the 500 response) as a way to indicate any problem with specific instances of a resource. An example of an instance resource in this case would be: http://server/ticket/80 # instance http://server/ticket # not an instance So this is the behavior that is being proposed. If ticket 80 does not exist return a http response code of 500. Within the body of the error return the "real" error as an additional error code and description. If the ticket resource doesn't exist return a response code of 404.

  • Is it a waste of time to free resources before I exit a process?

    - by Martin
    Let's consider a fictional program that builds a linked list in the heap, and at the end of the program there is a loop that frees all the nodes, and then exits. For this case let's say the linked list is just 500K of memory, and no special space managing is required. Is that a wast of time, because the OS will do that anyway? Will there be a different behavior later? Is that different according to the OS version? I'm mainly interested in UNIX based systems, but any information will be appreciated. I had today my first lesson in OS course and I'm wondering about that now.

  • College for Game Development [closed]

    - by Cole Adams
    I am currently a Freshman Computer Science Major at Samford University, but I am realizing that the actual field I want to get into is Game Development. I go to all of these classes that are supposed to make you well rounded that have nothing to do with what I want to do and frankly, after 18 years of schooling, I am sick of having to be in classes like that. I want to go to a Game Design/Development school where that is the priority and I am not overburdened with useless classes. At this point I am so tired of the Samford classes already that I am heavily considering taking next semester off and just getting a job and focusing on learning programming on my own or something like that. My question is what would be some good schools to apply to for enrollment in 2013 and what does it take to get into these schools? Thanks in advanced.

  • Why will Google Analytics not allow our URL?

    - by Linda H
    In Google Analytics we're trying to add a property for each website of a WordPress multisite network. It works well for all of the sub-site but one. In the Default URL field we used the following: www.mywebsite.no/ - works www.mywebsite.no/nurse - works, as does a few other sub-sites www.mywebsite.no/doctor - doesn't work In the last case we get the following error: Value is not a valid domain. (e.g. example.com, www.example.com) We can't change the name of the sub-site but GA just won't accept the URL. Why is this and what can we do to solve this?

  • Is the wireless driver from Live USB different from the standard install?

    - by Rafael Magalhães
    Linux newbie here. I've been trying to use Ubuntu (x64) as my main OS since 11.10, but my wireless connection on it has been very unstable, droping every other 5-10 mins. For this reason I see myself forced to use Windows 7 (dual booting), where connection works flawlessly -- which really bothers me. My card is an Atheros 9k, which claims a reasonable amount of wireless complaints on Ubuntu forums. I've tried every suggestion given on past questions to this site but to no avail. However, while running Ubuntu Live USB for some of the tests, I noticed that my wireless connection never failed on it and wondered if its network configuration differs from the one on the default Ubuntu install. If this is the case, how could I reproduce the Live USB network environment on my hard drive install?

  • Using shortkeys to search the internet for a term selected in a text editor/viewer

    - by cipricus
    It seems possible (as I learned from a comment to this question made by user55822) to use a command in order to search a term on the web by using "keybinding" the way Aretha is used. What the aforementioned user says is that "you could search mouse selection anywhere by using an app like Artha, or by keybinding sh -c 'firefox "http://translate.google.com/#en/fr/$(xclip -o)"' (example given translate english into french)" A lot of things are obscure for me here. I could use Artha or keybinding (as alternative), or both? How to do that in each case? and "The command I gave you will open google translate in Firefox with your mouse selection (text highlighted) as a query. Use sh -c 'firefox "https://www.google.com/search?q=$(xclip -o)"' if you want regular Google over Google translate. And obviously, that would work everywhere" I do not know what to do with that formula. What should I do exactly? How to use it? In what application?

  • Spreadsheet or writing an application?

    - by Lenny222
    When would you keep simple to medium-complex personal calculations in a spread sheet (Excel etc) and when would you write a small program or script for it? For example when you want to calculate what size of mortgage you can afford to buy a house. I could create a spreadsheet and have a nice tabular representation. On the other hand, if i would write a small script in a nice language (in my case Haskell), i'd have the security of a nice type system, preventing typos etc. What are the pro/cons in your opinion?

Is there any available solution or I should use some jquery like lazy load to load iframes once the scroller reaches them? Any help is greatly appreciated.

  • Where to start studying for developing ubuntu?

    - by Mad-scientist
    Hi am Computer Science student currently in college and very interested in developing open source software especially ubuntu.Is there a one stop go-to place for reading about developing ubuntu. For example I scoured through the official tutorial and documentation of Python and I was good to go.I could write useful applications. Is there any equivalent for Ubuntu or unity? I tried downloading the alpha 2,put kept crashing every 5 minute. I was told in IRC,it was due to some Xorg stack change. Now I cant even look at new Unity,let alone help develop it. Any help or guidance appreciated.

  • problem on static link to libsmbclient.a

    - by Rex
    I've tried to develop a library using libsmbclient-dev to access net share folders. I wish to static link libsmbclient.a in my project , but a lot of error happens when I tried to static link it, it seems that the libsmbclient.a doesn't include some objects it needed , while everything goes well with libsmbclient.so. Because my project need to support various linux versions like centOS , Ubuntu ..., we wish not to install libsmbclient-dev everywhere. Can anybody tell me that if I can static link this libsmbclient.a in an easy way ? Or what kind of installation strategy should I take to cause less trouble to users? If anyone have use this library to develop projects before , can you tell me how you deal with this case? Thank you very much!!!

  • The Enterprise is a Curmudgeon

    - by John K. Hines
    Working in an enterprise environment is a unique challenge.  There's a lot more to software development than developing software.  A project lead or Scrum Master has to manage personalities and intra-team politics, has to manage accomplishing the task at hand while creating the opportunities and a reputation for handling desirable future work, has to create a competent, happy team that actually delivers while being careful not to burn bridges or hurt feelings outside the team.  Which makes me feel surprised to read advice like: " The enterprise should figure out what is likely to work best for itself and try to use it." - Ken Schwaber, The Enterprise and Scrum. The enterprises I have experience with are fundamentally unable to be self-reflective.  It's like asking a Roman gladiator if he'd like to carve out a little space in the arena for some silent meditation.  I'm currently wondering how compatible Scrum is with the top-down hierarchy of life in a large organization.  Specifically, manufacturing-mindset, fixed-release, harmony-valuing large organizations.  Now I understand why Agile can be a better fit for companies without much organizational inertia. Recently I've talked with nearly two dozen software professionals and their managers about Scrum and Agile.  I've become convinced that a developer, team, organization, or enterprise can be Agile without using Scrum.  But I'm not sure about what process would be the best fit, in general, for an enterprise that wants to become Agile.  It's possible I should read more than just the introduction to Ken's book. I do feel prepared to answer some of the questions I had asked in a previous post: How can Agile practices (including but not limited to Scrum) be adopted in situations where the highest-placed managers in a company demand software within extremely aggressive deadlines? Answer: In a very limited capacity at the individual level.  The situation here is that the senior management of this company values any software release more than it values developer well-being, end-user experience, or software quality.  Only if the developing organization is given an immediate refactoring opportunity does this sort of development make sense to a person who values sustainable software.   How can Agile practices be adopted by teams that do not perform a continuous cycle of new development, such as those whose sole purpose is to reproduce and debug customer issues? Answer: It depends.  For Scrum in particular, I don't believe Scrum is meant to manage unpredictable work.  While you can easily adopt XP practices for bug fixing, the project-management aspects of Scrum require some predictability.  My question here was meant toward those who want to apply Scrum to non-development teams.  In some cases it works, in others it does not. How can a team measure if its development efforts are both Agile and employ sound engineering practices? Answer: I'm currently leaning toward measuring these independently.  The Agile Principles are a terrific way to measure if a software team is agile.  Sound engineering practices are those practices which help developers meet the principles.  I think Scrum is being mistakenly applied as an engineering practice when it is essentially a project management practice.  In my opinion, XP and Lean are examples of good engineering practices. How can Agile be explained in an accurate way that describes its benefits to sceptical developers and/or revenue-focused non-developers? Answer: Agile techniques will result in higher-quality, lower-cost software development.  This comes primarily from finding defects earlier in the development cycle.  If there are individual developers who do not want to collaborate, write unit tests, or refactor, then these are simply developers who are either working in an area where adding these techniques will not add value (i.e. they are an expert) or they are a developer who is satisfied with the status quo.  In the first case they should be left alone.  In the second case, the results of Agile should be demonstrated by other developers who are willing to receive recognition for their efforts.  It all comes down to individuals, doesn't it?  If you're working in an organization whose Agile adoption consists exclusively of Scrum, consider ways to form individual Agile teams to demonstrate its benefits.  These can even be virtual teams that span people across org-chart boundaries.  Once you can measure real value, whether it's Scrum, Lean, or something else, people will follow.  Even the curmudgeons.

  • have a missing file, and cant run ubuntu upon start up, and hasnt the flash drive i used didnt work either, any help?

    - by trent
    when I first downloaded Ubuntu to install it, it downloaded quick and caused no problems to my laptop. but then when it came time to install it as one of my operating systems, it wouldn't run because it said a file was missing or damaged. so then I uninstalled it and re-installed it but I still had that same problem. so I tried a flash-drive version but that didn't work either because it wouldn't boot from that, nor would it detect my flash drive, (in this case, an old 4 GB mp3 player). any help or tips and ideas would be great, I just need a decent operating system because windows is getting to be terrible at the moment, just note I wanna run Ubuntu along side windows 8.1

  • How to configure Google Analytics experiments manually

    - by John
    I wish to run multivariate tests on an e-commerce site that run across all product pages. I will be setting and deciding the variations myself all I need to do is track the results in GA. I think may be possible (although only A/B testing is available via the GA UI): https://developers.google.com/analytics/devguides/platform/features/experiments#serving-framework EXTERNAL – You will choose variations, handle experiment optimization, and only report the chosen variation to Google Analytics. For example, this should be used by 3rd-party optimization platforms that want to integrate with Google Analytics for reporting purposes. In this case, the Google Analytics statistical engine will not run. However how do I configure this and push the data to GA in my page?

  • Is it dangerous to substitute unit tests for user testing? [closed]

    - by MushinNoShin
    Is it dangerous to substitute unit tests for user testing? A co-worker believes we can reduce the manual user testing we need to do by adding more unit tests. Is this dangerous? Unit tests seem to have a very different purpose than user testing. Aren't unit tests to inform design and allow breaking changes to be caught early? Isn't that fundamentally different than determining if an aspect of the system is correct as a whole of the system? Is this a case of substituting apples for oranges?

  • Is conditional return type ever a good idea?

    - by qegal
    So I have a method that's something like this: -(BOOL)isSingleValueRecord And another method like this: -(Type)typeOfSingleValueRecord And it occurred to me that I could combine them into something like this: -(id)isSingleValueRecord And have the implementation be something like this: -(id)isSingleValueRecord { //If it is single value if(self.recordValue = 0) { //Do some stuff to determine type, then return it return typeOfSingleValueRecord; } //If its not single value else { //Return "NO" return [NSNumber numberWithBool:NO]; } } So combining the two methods makes it more efficient but makes the readability go down. In my gut, I feel like I should go with the two-method version, but is that really right? Is there any case that I should go with the combined version?

  • Cannot sleep/standby in Ubuntu 12.04

    - by mstaessen
    Yesterday, I installed Ubuntu 12.04 Desktop i386 on my netbook (HP Mini 311c). I am unable to use the sleep mode. When I press the suspend button (or do sudo pm-suspend), the screen flickers but the computer does not power off. Even worse, the screen comes back up and I'm back where I left off. Hibernating does work (although it is not available in Power Management). I have to use pm-hibernate to make that work. I'm using the 3.2.0.20 kernel and Gnome 3.3.92 (Unity, especially compiz, is a resource hog). Before Ubuntu 12.04, I was using Mint Linux 12 with the 3.0 kernel and everything worked fine back then. Any help is much appreciated because this is driving me crazy.

  • Making Class Diagram for MVC Pattern Project

    - by iMohammad
    I have a question about making a class diagram for an MVC based college senior project. If we have 2 actors of users in my system, lets say Undergrad and Graduate students are the children of abstract class called User. (Generalisation) Each actor has his own features. My question, in such case, do we need to have these two actors in separate classes which inherits from the abstract class User? even though, I'm going to implement them as roles using one Model called User Model ? I think you can see my confusion here. I code using MVC pattern, but I've never made a class diagram for this pattern. Thank you in advance!

  • Named arguments (parameters) as a readability aid

    - by Damian Mehers
    A long time ago I programmed a lot in ADA, and it was normal to name arguments when invoking a function - SomeObject.DoSomething(SomeParameterName = someValue); Now that C# supports named arguments, I'm thinking about reverting to this habit in situations where it might not be obvious what an argument means. You might argue that it should always be obvious what an argument means, but if you have a boolean argument, and callers are passing in "true" or "false" then qualifying the value with the name makes the call site more readable. contentFetcher.DownloadNote(note, manual : true); I guess I could create Enums instead of using true or false (Manual, Automatic in this case). What do you think about occasionally using named arguments to make code easier to read?

  • Why does qt-creator need to connect to google-analytics?

    - by Nanda
    I just installed qt-creator to work on non-qt C++ projects. The installed version is 2.5.0 (Based on Qt 4.8.2 32-bit) If I click on any of these pages: I get this error: I realized that /etc/hosts file has the following entry: 127.0.0.1 www.google-analytics.com I don't want to remove the entry from the hosts file because it's always been there along with thousands of other similar adservices/porn/malware addresses. I do not intend to say that qt-creator is looking to create problems in my computer, but I am genuinely interested to know why qt-creator needs to connect to google-analytics? Can this be disabled and qt-creator can still be functional?

  • Independent projects as a student to show off abilities

    - by tufcat
    I'm an inexperienced student (having learned up to data structures and algorithms through various online resources) of computer science, and I'm hoping to get a job as a developer some time after I've gotten a few independent projects done. My question is, how should I choose which projects to work on? I've been looking around stackoverflow-- people usually say to pick whatever you're interested in, but I don't have enough experience to even know what specifically I'm interested in, and possibly more importantly, I don't know what some common beginner project types are. Essentially, I'm at the gap between course work (and the projects entailed in those classes) and real programming, and I don't quite know how to start. If any of you have any ideas, I'd really appreciate it.
